Abstract

The Infrared Astronomy Group (Department of Astronomy and Astrophysics) at Tata Institute of Fundamental Research (TIFR) is presently developing controllers for the Teledyne HxRG Focal Plane Arrays (FPAs) to be used on board the Infrared Spectroscopic Imaging Survey (IRSIS) satellite payload. In this manuscript we discuss the results of our tests with different FPA controllers like the Astronomical Research Cameras (ARC) controller, Teledyne’s SIDECAR ASIC as well as our new in-house designed Array controller. As part of the development phase of the IRSIS instrument, which is an optical fibre based Integral Field Unit (IFU) Near-Infrared (NIR) Spectrometer, a laboratory model with limited NIR bandwidth was built which consisted of various subsystems like a Ritchey-Chretien (RC) 30 cm telescope, optical fibre IFU, spectrometer optics, and the Teledyne H2RG detector module. We discuss the various developments during the building and testing of the IRSIS laboratory model and the technical aspects of the prototype in-house H2RG controller.

用于IRSIS卫星有效载荷的Teledyne HxRG焦平面阵列控制器的评估和新型内部控制器的开发

塔塔基础研究所（TIFR）的红外天文学小组（天文学和天体物理学系）目前正在为Teledyne HxRG焦平面阵列（FPA）开发控制器，该阵列将用于红外光谱成像调查（IRSIS）卫星有效载荷。在这份手稿中，我们讨论了我们对不同FPA控制器的测试结果，如天文研究相机（ARC）控制器、Teledyne的SIDECAR ASIC以及我们新的内部设计的阵列控制器。作为IRSIS仪器（一种基于光纤的集成场单元（IFU）近红外光谱仪）开发阶段的一部分，建立了一个具有有限近红外带宽的实验室模型，该模型由各种子系统组成，如Ritchey-Chretien（RC）30厘米望远镜、光纤IFU、光谱仪光学器件和Teledyne H2RG探测器模块。我们讨论了在IRSIS实验室模型的构建和测试过程中的各种发展，以及内部H2RG控制器原型的技术方面。

期刊介绍： The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
